6 t'llairns. (ill. 229-27) This invention relates to a windowed cartonwith integral dividers and a blank from which such carbon is formed.

The carton blank serially includes back, bottom, front and top panelswith a closure flap on the top panel having detachable interlockingconnection with the back panel. Flaps on the ends of several of thepanels interlock to close the ends of the resulting box. A windowopening is cut in two contiguous panels, preferably the front and toppanels, and the opening is desirably covered by a sheet of transparentmaterial adhesively connected to the panels about the opening to providea window which is partly in the front and partly in the top of the box.

A particular feature of novelty comprises a flap which projects from therear panel at the end of the series to provide integrally with the restof the blank a pair of re-enforcing plies near the ends of the backpanel and a pair of dividers initially united at their ends but adapted,in the erection of the box, to be broken apart and folded across the boxtoward the front thereof. The re-enforcing or anchorage portions of thisflap are of greater projection than the portions thereof which form thedividers or partitions, whereby they can be roller coated with adhesivewithout adhesively coating the dividers, thus permitting the flap as awhole to be anchored tightly to the rear wall panel portion of the blankwithout in any way adhering to such rear wall panel portion the areas ofthe flap which are later to constitute the dividers.

Fig. 3 is a view on a somewhat enlarged scale showing the box in planwith its cover broken away in horizontal section.

Fig. 4 is a fragmentary detail view showing in perspective one end of apartially erected box with its cover and front wall panel broken away.

Fig. 5 is a plan view on a reduced scale of the box blank as initiallystamped out and roller coated with adhesive.

Fig. 6 is a plan view similar to Fig. 5 showing the box blank completedfor sale.

The box blank as shown in Fig. 5 comprises a rear wall panel 8, a bottomwall panel 9, a front wall panel lil and a cover panel 11, all connectedin series with score lines desirably provided at 12, 13 and 14delineating the boundaries between panels. The rear wall panel is slitat 15 to receive the headed locking tab 16 provided at the margin offlap 17 which is marginally connected to the panel 11. The connectionbetween cover panel 11 and flap 17 is desirably delineated by score line18. A window opening 19 which desirably is cut across the score line 14into the cover panel 11 and front wall panel is preferably covered by apiece of transparent cellulosic sheeting such as that shown at 20, thetransparent closure 2,854,182 Patented Sept. 30, 1958 for the windowbeing cemented to the inner face of the blank as shown in Figs. 3, 5 and6.

Bottom panel 9 is provided with flaps 22 and 23 at its ends, these flapsbeing adapted to be folded upwardly at the ends of the box and enclosedwithin the interlocking flaps 24 and 25 respectively provided at bothends of panels 8 and 10. The tongues 26 of flaps 25 are engaged, in theerection of the box, in slits 27 of the respective flaps 24. The tabs 28of flaps 25 are thereupon folded inwardly beneath the cover 11.

A particular feature of the invention comprises the pro vision at theend of the series-connected panels 8, 9, 10 and 11 of a flap 30 integralwith panel 8 and comprising anchorage areas 31 and 32 adjacent the endsof panel 8 and marginally delineated, preferably, by score lines at 33and 34 respectively. Between the anchorage areas 31 and 32, the flap 30comprises partition-forming elements 35, 36 of less extent than theareas 31 and 30 and connected thereto at their ends, the connectiondesirably being represented by score lines at 37 and 38. Thepartition-forming elements 35, 36 are completely severed from panel 8 bycuts along their curved margins 39 and 40. They are partially severedfrom each other by cuts 41 and 42 but are united integrally by means ofthe uncut tongue 43. The wall 8 may optionally have shallow notches 400to aid the operator in pushing the elements 35, 36 inwardly when the boxis erected.

The blank being completed to the form shown in Fig. 5, it is providedwith adhesive for the connection of the re-enforcement flap 30 with therear panel 8. Assuming that the anchorage areas 31 and 32 have greateroutward extent than the partition-forming elements 35 and 36, thisconnection is simply and easily made by passing the projecting portionsof the anchorage areas beneath a gluing wheel which applies adhesivethereto as shown at 45 in 3 ice Fig. 5. The strip of adhesive is outsideof the partition forming areas 35 and 36, leaving these free ofadhesive.

The entire flap 30 is now folded down onto the rear wall panel 8 asshown in Fig. 6, whereupon the adhesive 45 laminates the anchorage areas31 and 32 to the rear wall panel 8, leaving the divider orpartition-forming areas 35 and 36 in face contact with, but free ofconnection with, the rear wall panel 8 and still attached terminally toeach other by means of the tongue 43.

In the erection of the box, which is shown in progress in Fig. 4, thepartition-forming tabs 35 and 36 are swung inwardly at right angles tothe rear wall panel 8, thus severing their ends from each other bybreaking the connecting tongue 43. This leaves short torn edges at 430,all other free margins of the partitions being die cut.

The box being erected, it is filled with any desired contents, thearticles shown at 50 being for exemplification only. The cover is thenclosed over the contents and its headed tab 16 is engaged in slot 15.The window closure 20 exposes the contents to view both from the frontand from the above the box.

It will be understood that the partition-forming means herein disclosedhas utility in boxes other than the specific form of box hereindescribed, and the flap of which the partition-forming means is a partmay be otherwise connected to the blank, the connection to the rear wallpanel being preferred. it will also be understood that it is notessential to the invention that the partitionforming means be adapted toform two partitions, my concept being more broadly directed to anorganization in which anchorage portions of the flap are connected insome manner to a panel of a box and having integral partition-formingmeans extending free of such panel between the anchorage portions of theflap and integrally connected either directly or indirectly with boththereof.
